Abstract
Aquarium with a multiple conduit fixture through one wall, the fixture including an air inlet connected to a plurality of air outlets and a water conduit, each of the air outlets and the water conduit having a throttle valve means at the outside end of the fixture to regulate the flow of air and water respectively, and a perforated support sheet to cover the inside bottom of the aquarium and any conduits for air or water, and to support thereon a gravel bed and any decorative items on the bed, the aquarium featuring several air bubbling locations.
Claims18
An aquarium having at least one vertical wall and a bottom wall, said vertical wall having an opening means therethrough adjacent said bottom wall, a fixture mounted through said opening and sealed thereto in a watertight manner, air and water passageways through said fixture communicating between the inside and outside of said aquarium, a perforated support sheet spaced upwardly from and covering substantially all of said bottom wall, said support sheet adapted to receive and be covered with a bed of gravel and other items to resemble the floor of a body of water, external air and water conduits connected to respective said air and water passageways outwardly of said aquarium, internal air and water conduits connected to respective said air and water passageways inwardly of said fixture and leading from said fixture under said support sheet and discharging at selected locations under said bed of gravel, and adjustable valves in said fixture communicating with said passageways to adjust the air flow to any selected rate and to adjust the flow of water into or out of said aquarium or to cease flow of water in either direction.
In an aquarium having four vertical sidewalls and a bottom wall joined together to hold water therein in a leak proof manner, the improvement comprising an opening means through one of said vertical walls adjacent said bottom wall, a fixture in said opening extending from outside to the inside of said aquarium and sealed to prevent leakage of water around said fixture, said fixture having an elongated water passageway passing therethrough, an air inlet passageway at the outside end of said fixture connected to at least two air outlet passageways at the inside end of said fixture, and flow regulating means in each of said water passageway and said air outlet passageways operable from said outside end of said fixture, at least two flexible air conduits leading from respective said air outlet passageways to any selected discharge location adjacent said bottom wall;
- and a perforated support sheet adapted to cover said flexible conduits and said inside end of said fixture and said bottom wall and adapted to support a gravel bed and other aquarium items resting on the bed above said bottom wall of said aquarium.
A fixture for an aquarium to couple a plurality of fluid conduits for delivery into and out of an aquarium, said fixture being adapted to be positioned through an opening in a wall of the aquarium and extending outwardly from both sides of the wall of the aquarium and sealed in watertight relation to the wall of the aquarium, said fixture comprising an elongated body generally conforming to the opening in the wall of the aquarium and including adjacent one end thereof a head portion larger than the opening in the wall of the aquarium and at the other end thereof external screw threads, a nut threadedly engaged with said external screw threads, a plurality of elongated passageways extending lengthwise through said body, a lateral passageway connecting at least two of said elongated passageways for delivery of air thereto, internal threads in said at least two of said elongated passageways, and adjustable screws threadedly connected with said internal threads and adapted to control the flow of air therethrough.
